In terse entry on her official blog Monday, singing star Katy Perry shot down rumors that she is dating Good Charlotte rocker Benji Madden.

On Sunday, PEOPLE Magazine claimed the singer, who recently ended a lenghty romance with Travis McCoy of the Gym Class Heroes, was spotted in Las Vegas nightclub on Valentine’s night “cuddling” with Benji.

Katy writes of the rumors:

oh kittens! It’s two pseudo famous people sitting next to each other… doesn’t mean we were bumping uglies! You know I don’t just do that with anyone! That’s just how the media works, as you can tell. I was there celebrating a really fun show and a boozy valentines with all my good friends. We were like a group of 25! Benji is a nice young fellow, but my heart really belongs to kitty purry/markus molinari. Hope your vagina day was as FUN as mine. Definitely not too heart breaking :)
